摘要： An embodiment of a fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having a first surface and a second surface opposing the first surface and having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering toward the inlet. The body, in use, causing fluid flowing through the channel to diverge into at least a first path between the first surface and a first side of the body, and a second path defined by at least by the second side of the body. A geometry of the first path and the second path selected is based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： An all mechanical counter dart including a mandrel, a plurality of shoulder members disposed upon the mandrel and movable from a more downhole portion of the mandrel to a more uphole portion of the mandrel, individual ones of the plurality of shoulder members moving from an inactive position to an active position and back to an inactive position while traversing the mandrel, and an upset on the mandrel supporting the individual ones of the plurality of shoulder members when in the active position.

摘要： A downhole system includes a packer assembly including a backup ring. The backup ring includes a plurality of nested leaves nested sequentially in a circumferential direction with adjacent circumferentially positioned leaves to collectively form a substantially circular shape. Each leaf includes a receiving section and an insertion section, the receiving section receiving an insertion section of an adjacent leaf. Upon radial expansion of the backup ring, the plurality of nested leaves fan out in the circumferential direction.

摘要： A method of controlling flow in a tubular including developing a pressure in the tubular with an electric submersible pump (ESP), directing a flow of fluid through a flow control device arranged on the tubular downhole of the ESP in response to the pressure, sensing a parameter of the flow of fluid, and adjusting, in real time, a flow parameter of the flow control device with a coil tubing in response to the parameter of the fluid.

摘要： An object including a housing, a cone movably received in the housing, a piston body attached to the cone, a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body, and a trigger configured to open the valve at a selected circumstance. A method for moving a selected downhole tool including running an object into a borehole, counting features in the borehole using a sensor in the object, opening the valve at a selected count, flooding the interface with hydrostatic pressure, driving the piston body away from the housing, and moving a radially expandable shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.
